To allfwh'om itmag concern.

Be it known that I, .ADAM J. SMITH, a

citiiz en of the United States of America, and-resident of Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and useful Improve= merits in Pin-RemovingTools, of which the following is a specification.

V This invention relates to improvements in tools applicable for the removal of spot ting pins from their rack when their re+ placement by new pins is required, reference being had to that bowling alley equipment wherein vertically movable rack is pro vided with a group of pins that are projected up through corresponding openings in the floor of'the alley andserve as guides for the tenpins as they are positioned on the "floor. In such structures the pins are collectively elevated by movement of the rack so that they project above the floor while the pins are being spotted and are subsequently withdrawn by lowering the rack in order that the pins be not injured when the ten pins are .struck. It frequently occurs through inadvertence that the pins become bent or broken and their removal from the rack and replacement 'becomes necessary, and as the rack is located sore or less inaccessibly beneath the floor, it is desirable that the pins be removable from the rack through the corresponding openings in the floor through which the pins operate, and frequently such operations are attended with diiiiculty. The object of the present invention therefore, is to provide an instrument applicable for the removal of spotting pins from their rack through the corresponding openings in the floor of the alley and which will disconnect the pins from the rack and secure them in the tool for their removal. Another object of the invention is to provide in the construction of the tool means for ejecting the pin secured therein after its withdrawal from the rack.

These objects are accomplished by the construction illustrated in the accompanying drawings, in which: V

Fig. 1 is a vertical section showing the invention as it is applied to a spotting pin prior to the removing operation;

' Fig. 2 is a vertical elevation partly broken away shown in readiness for the ejecting pera ion; and.

The characters appearing in the d escrip tion refer to parts shown in-the drawings andv designated thereon" bycorresponding characters. I

' Theinvention comprises ahandle formed ofa tubul'ar member 1 having'diametrically oppositelongitudinal slots 2' and an EXCEED- sion 3 of reduced diameter at its 1 lower endi The upper portionof the member is pro'* vided with a tubular-V casing 4e by'whi'ch said slots are concealed; The-upperend of; the

member 1 has an annular; chamber made therein and diametricallyopposite recesses 6 at the base ofthe chamberfon-thmpur pose her-eina-ften described, the said longi.

tu'dinal slotsextending intosaid 'chambw.

s A plunger 7extends into the tubular mem her 1 through the top thereof and is provided with a transversely positioned pin 9, the ends of which project respectively from the corresponding sides of the plunger so as to extend into the corresponding slots 2 of the member 1, or into the corresponding recesses 6, accordingly as the plunger is position-ed. The upper end of the plunger has an enlarged head 8 and the lower end has an extension 10 of reduced diameter. The plunger is held in connection with the tubular member by a cap 11 through which the plunger extends and which is screwed onto the top of the member 1, so that the cap limits the upward movement of the plunger because of the engagement of the ends of the pin 9 therewith. V

In utilizing the invention, the plunger is raised in the handle so that the ends of the pins 9 extend within the recess 5, and the plunger is then turned to permit the ends of the pin to become seated in the recesses G and the downward relative movement of the plunger in the handle is thus arrested. The extension 3 is then introduced through the opening 12 of the floor 13 and over the spotting pin 14 which is slotted at its lower end to admit of its being compressed during removal from the rack 15. The extension 3 is then driven down onto the pin by striking the head 8 of the plunger downwardly with a hammer so that the pin is thereby compressed and held frictionally in v the extension, The tool is then Withdrawn with the pin held in its extension. The plunger is then turned in the handle so that the projecting ends of the pin 9 are alined with the slots 2, thus permitting the plunger to be moved downwardly onto the top of the pin. Then, by applying force downwardly to the plunger, the pin may be readily ejected from the extension 3 in which it is frictionally held. Thus, it will be understood that the plunger in its relation with the handle has two distinct operating positions, viz one for securing the spotting pin in the extension prior to the removal of the pin from its rack, and the other for ejecting the pin from the tool subsequent to its removal from the rack.

What I claim is:-

1. A tool for the removal of spotting pins from their rack comprising a tubular member with opposite longitudinal slots therein and an extension of reduced diameter at its lower end, there being an annular chamber in its upper end and oppositely disposed recesses at the base of said chamber; a casing for said member concealing said slots; a plunger longitudinally movable in the tubular member; a pin extending transversely in the plunger with its ends projecting from the corresponding sides of the plunger and having selective engagement in sa1d slots or recesses accordingly as the plunger is positioned; and a cap at the top of the tubular member operable to limit upward movement of the plunger by engagement with the ends of said pin.

2. A tool for the removal of spotting pins from their rack comprising a tubular handle having internally disposed longitudinal slots therein and oppositely disposed recesses at the upper end of the handle and spaced respectively between the slots; and a plunger member including means selec tively engageable in said recesses and operable to limit the plunger to its uppermost position, and in said longitudinal slots to admit of longitudinal movement of the plunger in said handle.

3. In a tool for removing spotting pins from their rack, a handle having a tubular end for the reception of a spotting pin and operable to compress the pin when driven thereon; a plunger member in the handle; and means in connection with the plunger and the handle operable selectively to sustain driving relation of the plunger with the handle while the handle is being forced onto the pin, and to admit of movement of the plunger in the handle to eject the pin therefrom.

In testimony whereof I affix my signature.

ADAM J. SMITH.
